VPC supports IPv6 feature. When there are IPv6 service needs, you need to assign an IPv6 CIDR IP range to your VPC first, and then cloud resources in the VPC can be assigned IPv6 addresses within the VPC's IPv6 CIDR, enabling IPv6 communication for your services. This section describes how to assign IPv6 CIDR to the VPC through the console.
Note
